چکیده
Determining the dynamic response of frozen soil is important for the study of the deformation, strength and stability of frozen soil under dynamic loading conditions for engineering design in cold regions. This paper discusses the recent progress in research on the dynamic response of frozen soil from the following three aspects: (1) influence of various testing conditions (confining pressure, temperature, water content, frequency, strain amplitude and maximum load) on dynamic properties (dynamic elastic modulus, dynamic shear modulus and damping ratio), (2) dynamic stress-strain properties and the influence of various testing conditions on dynamic strength, (3) effect of testing conditions on dynamic creep factors (time to failure, failure strain and minimum strain rate) and the dynamic creep models.

Simple Pile-Soil Interaction Effect on Seismic Response of Fixed Offshore Platforms
In this paper effect of pile-soil consideration in obtaining seismic response offshore structure is assessed due to earthquake loading. InducedSeismic force is one of the most important excitations for the dynamic response of an offshore structure. According to API, Seismic forces should be accounted in platform design for seismically active regions in order to determine the allowable seismic r...
متن کاملEffect of Riser-Seabed Interaction on the Dynamic Behavior of Risers
In recent years, the production of oil and gas has been developed in deep water depths which exceed 500m. Deep water developments are being followed strongly in different parts of the world (Caspian Sea, Gulf of Mexico, etc.). The movement of floater causes severe stress at the touchdown point (TDP) in steel catenary risers (SCR). The main objective of this study was to simulate the exact behav...
